Unerupted Permanent Canines and Incisors Flashcards
how can you tell if a tooth is a primary tooth
colour
wear
mobility
shape
what are the main reasons for a lateral ceph
look at severity of underlying skeletal pattern
confirm incisor relationship
view of unerupted tooth
how can you assess presence of unerupted canines
palpate buccally and palatally
check mobility of c’s
angulation of adjacent incisors
mobility of incisors
colour of lateral incisor
what are the causes of unerupted canines
long path of eruption
genetic links
crowding
ectopic position of tooth germ
what other dental conditions can unerupted canines be linked with
ectopic canines
missing laterals
peg laterals
hypodontia
what malocclusion is unerupted canines most common in
class 2 div 2
what are the treatment options for ectopic canines
accept
extract c
bonding gold chain
expose to erupt on its own
surgical removal
autotransplantation
what position would an ectopic canine be in for it to not have a good chance of eruption
very high
horizontal
mesial
what age range has the most successful chance of canine erupting
10-13
what are the risks of leaving the canine unerupted
root resorption of adjacent teeth
ankylosis of canine
cyst formation
make restorative tricky
resorbed canine crown
why would you choose to remove the unerupted canine surgically
if not good path of movement into arch
early root damage of incisor
patient crowded and 2 and 4 have nice contact already
what are the consequences of accepting unerupted maxillary incisors
ankylosis
root resorption
more drift of lateral incisor
cyst formation
what are the risks of bringing an unerupted maxillary incisor into the line of the arch
not the greatest periodontium
ankylosis
external root resorption
why would you remove an unerupted maxillary incisor
no obvious path of eruption due to risk of damaging adjacent teeth
patient doesnt want complicated treatment
how do you manage unerupted central incisors
make space
remove obstruction if patient less than 9yrs old to
leave to erupt itself over 6-12 months
